The fastest way is to use "tftpdnld".

How to Download a Software Image to a Cisco 2600 via TFTP Using the tftpdnld ROMMON Command

http://www.cisco.com/en/US/customer/products/hw/routers/ps259/products_tech_note09186a008015bf9e.shtml

Hi leolahoo,

                Thankx for ur kind help,when i am trying to upload via tftp getting error which below config   

             router fe0 connects to symtem via cable. I basically pasted this config into rommon and the image loaded

IP_ADDRESS=192.168.1.99

IP_SUBNET_MASK=255.255.255.0

DEFAULT_GATEWAY=192.168.1.1

TFTP_SERVER=192.168.1.100

TFTP_FILE=c870-advipservicesk9-mz.124-24.T1.bin

tftpdnld -r

TFTP error 1 received (File not foundÌT¸°).

TFTP: Operation terminated

please note windows firewall is disabled.

check this also may be i am doing mistake while assinging ip address.

I put symtem ip address(on which tftp sever is running)

ip address=192.168.1.100

subnet mask 255.255.255.0

default gateway = 192.1689.1.1

On router fe0 interface ip address=192.168.1.1

but i dont understand where i have to assign ip address 192.168.1.99 as i shown above this command is needed  according to syntax.

onemore thing is that when i used below command:

xmodem -c c870-advipservicesk9-mz.124-24.T1.bin

ios downloading  completed but  tell me how to save the image to Flash, after xmodem command

when i put the commands

confreg 0x2101

reset

the router comes in rommom mode again.

.

I dont know which command save image to flash.

I dont have sufficient privilleges to access bekow link http://www.cisco.com/en/US/customer/products/hw/routers/ps259/products_tech_note09186a008015bf9e.shtml

TFTP_FILE=c870-advipservicesk9-mz.124-24.T1.bin
tftpdnld -r
TFTP error 1 received (File not foundÌT¸°).

This means that the filename is either not correct, not found or your TFTP server is pointing to the wrong folder.

Sorry for the delay            

really busy for finding the solution at last i found it.

I uploaded ios in rommon mode by using console the steps  used are below.

step1:put ios in computer c: drive or any folder.

step2:open hyperterminal with default setting on router type the command as shown below

step3: rommon 29 > xmodem -c c:\c870-advsecurityk9-mz.124.T.bin

message appears

"Do not start the sending program yet...

WARNING: All existing data in bootflash will be lost! Invoke this application only for disaster recovery." Do you wish to continue? y/n  [n]:  y

Ready to receive file c:c870-advsecurityk9-mz.124.T.bin

step4:go to tranfer select send file .

step5: specify the image file name and location and enter xmodem as a protocol .

step6:click on send to start transfer

. Specify the image file name and location and enter xmodem as the protocol.

the messege receved when transfer successfully complete.

"CDownload Complete!

" Copying file c:c870-advsecurityk9-mz.124.T.bin to flash.

Writing flash:/c870-advsecurityk9-mz.124.T.bin

Write operation will take approximately 85 to 256 seconds

check whether ios save in flash by b elow command

step7:rommon 34 > dir flash:

Directory of flash:/ 2    -rwx  13993708

       c870-advsecurityk9-mz.124.T.bin 9484288 bytes available (13998080 bytes used)

step8: rommon 35 > confreg 0x2102

You must reset or power cycle for new config to take effect put i or reset to reload router

step9: rommon 36 > i now router boots from flash without any problem

. I am posting the  solution because others should not suffer like me.
